The Portuguese chief has expressed his concern over their lack of strength in depth. Carvalhal has already indicated he will field an under-strength side in Wednesday’s EFL Cup first-round clash at Cambridge United next Tuesday. The tie comes 48 hours after the Owls’ televised league opener with relegated Aston Villa.

Carvalhal said: “We want two players per position. We need a centre-back and a left-back because we just have Daniel [Pudil].

“We have three centre-backs and we also have Jose [Semedo] and Daniel who can cover the position.”
